To (ZZZ whom it 7710?] concern:

Be it known that I, lsnAnL :nu'rr, a citizen of the United States, and resident of New York, in the county of New York and State oit New Yoiut, have invented certain new and useful lnn'n-ovements in Selt- Fil ler ltlechaiiisin tor liountain Pens, of which the following is a specification.

My invention relates to self-filler mecha- 1U nism for "fountain pens; that is, to mechanism carried by the fountain pen or replenishing the supply of ink contained Within the pen.

ll'lore particularly stated, my invention contemplates mechanism operated in connection With a capsule of soft rubber used for retaining the ink, the purp se of my improvement being to enable the operator to compress the capsule througliout practically the entire length thereof in order to enable the capsule to fill itself with ink by suctioinmy device being constructed and arranged for use with ink capsules of con siderable length.

A further object is 't'o provide a filler mechanism of the type indicel-ted and which is adapted to be operated by a spring .pressed button at the extreme end of the pen barrel.

' A further and more detailed object is to provide a filler .me chanism comprising a parallel moving bar, a control button at the end of theupen barrels'prnig pressed 4 to hold said "bar normally in its collapsed position and saidbntto'n bei'n' d'apt'ed to be moved manually long-null ly out of the end of the jpe'nbai'i'elfor thercl'i'y mov-- ing the barr o-capsule compressing position. other objects and aims of the invention more or less specific than those referred to above, will be 'in art obvious and in part pointed out in the coi'irse oil the tollox'vin}; description of the e'lemeii 'combina -tions, 'arran ein'en ts of parts, and applications o f'pii'nciples constituting; the infventio'n, andthe scope of protection centers plated will be indicated in the appended claims. I

In the accompanying drawings, which are to be taken as a part of this specification and in Which I shall show merely {a prererr'el iorm of embodiment of -the invention:- v

Figure l is a longitudinal section. then substantially through the center of a itc-un with eyes 17 and 18 which are carried by 9 tai'n pen provided with my device and showinp; the ink capsule as fully distended.

Figure 2 is diagram indicating the manner in which my apparatus is used in connection with the ink capsule, for com-- nfessing the latter throughout practically its entire length.

Figure 3 is a section on the ii of Figure 1, looking in the direction indicated by the arrows.

.Fi i'ure 4 is a section on the line Y of Figure 1, looking in the direction indicated by the arrows.

The barrel of the fountain pen appears at the pen section at 6, the pen point at '7 and the adjustable ink feed at 8, these parts each being of the usual or any preferred form. v Y

The pen section '6 is provided witl i a threaded portion 9 of reduced diameter, 7 which fits into a mating threaded portion 10 of the barrel 5. I i p The ink capsule is shown at 11, and has considerable length as coi'npared with diameter and with the diameter of the 59 rr i Sliclably engaging the ink capsule 11 is a follow plateor bar 12, used as hereinafter described and pressing thereupon. This iollow plate has approximately the same length as theink'capsule.

The follow plate is made of hard rubber or sheet metal, preferablypolished, and is provided with two pairs of eyes '13 and 14, formed out of small integral portions of the fellow plate. Connected with the eyes 18, 14, and thus Journ'al'ed to theiofllow plate 12, are a pair oi "rocking links 15 and 16, these links being also connected and integral with a suapo'rting strip 19. This supporting stri'pfis lnade other-d rubb'er or sheet metal, as the case n'iay be, end at one of'it's ends extends into a recess '20 and at its other end is provision with a portion 21 formed into a tongue, as shown more parti'eiilarlyin Figures 1 and t.

Fitted "tightly into the bit fo 5 is ae01. lar '22, so formed to provide ssag'e 23 and two other passages 2 l24. The collar 22 is also provided With a slot 25,- e1-ging into the passage'23. The tongue '21 of the supporting strip '19 extends 'thro'itgzli the passage Zitand terminates in a ti 3 "26, which is bent slightly downward and into l llz i llfit I 25. Thus the supporting strip 19 is held firmly in position.

The follow plate 12, which is always in engagement with the ink capsule 11, is free to move away from the supporting strip 19 .so as to compress the ink capsule, the rocking links 15 and 16 being adapted to swing for this purpose, as may be understood by comparing Figure 2 with Figure 1.

The barrel 5 is at one of its ends provided with a portion 27 bent sli htly inward, as indicated at the right of Figure 1. Extending through this portion is a cylindrical member 28, provided with a head or button 29 and with an enlarged bearing portion 30. A spiral compression spring 31 encircles the cylindrical member 28, and engages the portion 27 of the barrel and also the bearing portion 30 of the cylindrical member 28. The tendency of the spring 31 is to force the cylindrical member 28 to the left, so that normally the movable parts thus il'nmediately affected occupy the positions indicated for them in Figure 1.

The cylindrical member 28 carries an eye Connected with this eye is a link 32-3, this link also being connected with an eye 34%, carried by the follow plate. lVhenever the head 29 is grasped by hand and pulled to the right according to Figure 1, the link 33 pulls upon the follow plate 12 so as to cause it to swing away from the supporting strip 19 and also to move slightlyendwise; that is, to the right according to Figures 1 and 2.

Connected with the cylindrical member 28 are two guide blades 85, each of arcuate form in cross section, as indicated in Figure 3. These guide blades are rigid relatively to the cylindrical member 28, and extend into the passages 24- with which the collar 22 is provided. as above described, and as indicated in Figure 3. Thus the guide blades 35 serve to guide the cylindrical member 28 and hold the same pro erly in position, while allowing the cy indrical member a limited travel.

he operator,,by grasping the head 29 and pulling upon it so as to movethe cylindrical member 28 to the right as indicated in Figure 2, causes the link 33 to pull upon the follow plate 12, and thus causes the follow plate to compress the ink capsule 11, as indicated in Figure 1. Compression of the ink capsule causes it to expel its con tents, in the manner well known in this art. This done and the front end of the pen being submerged in free ink, the operator releases the head 29; and thereupon the various movable parts are by the tension of the spring 31 caused to resume their respective normal positions, as indicated in Figure 1. The ink capsule 11, being resilient and resulming its normal shape, becomes filled with in r.

It will be noted that the ink capsule is compressed throughout practically all of its length, because the follow plate 12 is quite lengthy and all portions of it move as a unit in compressing the ink capsule. By this arrangement the ink capsule can be easily and quickly caused to expel its con tents and to take a new supply of ink. Moreover the ink capsule, when used with this arrangement, can be made of considerable length and yet able to work well. The expulsion of the contents of the ink capsule, whether said contents be air or stagnant ink, or a mixture of air and ink, is in any event complete, and whenever the ink capsule is compressed and allowed to regain its original form as here contemplated, it is filled completely with the new ink.

The head or button 29, and in fact the entire cylindrical member 28, may be of any desired shape or form either orna mental or otherwise.

I do not limit myself to the precise mechanism shown and described, as variations may be made therein without departing from my invention, the scope of which is commensurate with my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. In a fountain pen, comprising the usual barrel and having a collapsible elongated ink capsule therein, a follow plate for collapsing said ink capsule, a pair of links by which the follow plate is mounted to move in parallel planes during the collapsing of the ink capsule, an operating member slidably'mounted in the end of the barrel having a head externally of the barrel, a link connecting said operating member with said follow plate whereby withdrawal of the operating member will move the follow plate to capsule collapsing position, the end portion of the barrel having an inturned annular flange thereon constituting a shoulder facing inwardly of the barrel, the operating member having an annular shoulder thereon facing outwardly of the barrel and in opposition to the first shoulder, and a compression spring encircling the operating member interposed between said two shoulders and serving thereby to normally hold the operating member yieldingly in its innermost position and to hold the follow plate close against the wall of the barrel and therefore out of capsule collapsing posi tion.

2. In a fountain pen, comprising the usual barrel and having a collapsible elongated ink capsule therein, a follow plate for col lapsing said ink capsule, a pair of links by which the follow plate is mounted to move in parallel planes during the collapsing of the ink capsule, an operating member slidably mounted in the end of the barrel'having a head externally of the barrel, a link connecting said operating member with said follow plate whereby withdrawal of the operating member will move the follow plate to capsule collapsing position, a supporting strip extending longitudinally of the barrel by which said links are supported, a retaining member serving to retain the sup porting strip in fixed relation to the barrel and said retaining member having parts cooperating with parts of the operating member to guide the operating member.

3. In a fountain pen, comprising the usual barrel and having a collapsible elongated ink capsule therein, a follow plate for collapsing said ink capsule, a pair of links by which the follow plate is mounted to move in pa 'allel planes during the collapsin g of the ink capsule, an operating member slidably mounted in the end of the barrel having a head externally of the barrel, a link connecting said ope ating member with said follow plate whereby withdrawal of the operating member will move the follow plate to capsule collapsing position, a sup porting strip extending longitudinally of the barrel by which said links are supported, a collar arranged within the barrel engaging said supporting strip and serving thereby to hold the supporting strip in fixed relation to the barrel, said collar being shaped to provide a guideway between itself and the barrel, and a guide extension provided upon the operating member slidably received in said guideway to thereby serve in guiding the movements of the operating member.

4. In a fountain pen, comprising the usual barrel and having .a collapsible elongated ink capsule therein, a follow plate for collapsing said ink capsule, a pair of links by which the follow plate is mounted to move in parallel planes during the collapsing of the ink capsule, an operating member slidably mounted in the end of the barrel having a head externally of the barrel, a link connecting said operating member with saidfollow plate whereby withdrawal of the operating member will move the follow plate to capsule collapsing position, a pen section engaging within the opposite end of the barrel and being shaped to provide a recess between itself and the barrel, a supportingstrip extending longitudinally of the barrel by which said links are supported, a retaining collar arranged within the barrel adjacent the first mentioned end of. the barrel shaped to provide a recess between itself and the barrel, said supporting strip having its opposite ends received in said two recesses respectively whereby thesupporting strip is held in fixed relation to the barrel, and said collar also having parts cooperating with parts of the operating member to guide the operating member.

In testimony whereof I affix my signature.
